Hey yall - i'm needing some advice on realigning front forks on a kymco agility. Riding down the road, i gotta keep a firm pull on the left grip to keep the bike square on the road. I'm seeing slight evidence that the previous owner may have bumped or hit something that threw the front out of alignment slightly. Would just like some guidance, what to check, how to adjust, how to recheck, etc.
Thanks in advance!

I would probably start by undoing the wheel spindle, and fork clamps slightly. Just so it's free to move, but not sloppy.
Then with the front brake on, pump the forks a few times. Then tighten it all up again. It should now sit correctly. Fingers crossed.

Due to the two wheeler counter steering in mind, if your pulling on the left bar, then the bike is steering left and your having to steer it to the right?
Reason I ask is that roads are typically graded to the right (outside) and that can steer the bike to the right (outside).
But yours appears opposite.
I've had tweaked fronts but didn't typically notice any steer, just handlebars pointing slightly off.
I did a run to Sturgis once going straight west with a non stop side wind and wore a flat strip on the rear tire a bit off center.
The return trip (straight east) was a chore because I had to kind of balance on the edge of the previously worn strip.
It was made worse because the steering head bearings had hammered into the races and gotten significantly worse during the trip and I was fighting the steering to essentially lift the bearings out of the hammered dimples just to go straight.
Moral of that story is tire wear can cause issues.
A lot of times just wedging the wheel up against something and yanking on the bars can correct.

I haven't gotten to the alignment yet. My fix-it list is huge at the moment. Especially with upcoming winter... |

Bearings getting hammered into races is bad. That is why a little swaying and motion is good. Watch the woman moving on the bike in front of you... Oh shit, -slap face- not politically correct thinking.
That is why the U-joints on Cagers have a minimum angle of 1-1/2 degrees on the drive line to keep those roller bearings moving. Keep them bearings moving rawhide! -oops, wrong jingle. Are any of you OLD enough to remember the TV show that came from?

Are any of you OLD enough to remember the TV show that came from? i do remember many of them shows, used to watch gunsmoke n them with my grandpa as a kid. As for them bearings, i assume you're referencing the steering stem races. Yeah, i havent loosened them yet. Pretty sure its all stock setup currently. Even the stock restrictors were still in place. The only thing that wasnt stock when i bought it was a k&n style pod filter right on the carb mouth. No stock airbox. Hell, i could really use a stock airbox, i'd be happy to toss that damn pod filter right in the trash. It's been a nightmare tuning that carb. And generic airboxes dont fit. I tried a couple. Kymco has some funny mounting bolt locations compared to generic... but... thats for the build/troubleshoot thread i oughta be starting already. Effit, i'm off to do that now... |

Make sure axle isn't bent, make sure speedo gear drive is not binding when checking axle (does wheel spin as smooth/straight as one can expect from a scoot while unloaded in air) and drop that fork triple out of the steering neck and redo neck bearings and inspect the races to make sure even surface. Tire wearing ok?
